Silly Job Title: Solder Soldier. I am the Solder Soldier!

In this video we make a power cable running a DC barrel female socket into hook-clips.

We use the METCAL PS-900 Soldering Station for soldering.

We use the Riden RD6006 Bench Power Supply to provide power for testing.

We use the EEVblog BM2257 Digital Multimeter to test the cable.

We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Surge Sage. I am the Surge Sage!

In this video we continue to work our way through Learning the Art of Electronics. In this video we continue with 1L Lab: DC Circuits and do an experiment: try your DVM’s resistance measurement.

Today we do some experiments to determine the voltage used by our DVM when it is in resistance-measuring mode.

We use the Fluke 17B+ Digital Multimeter to measure resistance and voltage.

We use the EEVblog BM2257 Digital Multimeter to measure resistance and voltage.

We use the Multicomp Pro MP701033 Resistor Decade Box as our variable resistor.

We use the Carpenter Mechanical Pencil to take notes.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
